Ironically, Kuwait has been running ads in the Economist and elsewhere touting their openness and modernism.
Without seeing the actual order, we don't know if it calls out DSLR's or just large, professional looking cameras. I think, though, that is is a safe bet that Kuwaitis don't mind, too much, being photographed by people they know with cell phones and little cameras, but take exception at a stranger with what looks to them like a pro camera. Why? Because they assume the guy with the big camera is going to publish, while the guy with the phone or the small camera isn't. They are not alone in that assumption, as bogus as it may be.
How much you wanna bet some guy with a big Nikon or Canon and a long lens really annoyed the wrong person, who made the rounds of the ministries?
